研究探讨在半经典引力中，达穆尔 - 索洛杜金虫洞模拟黑洞性质时，观察者观察到的物体身份问题。通过引入唐赫利尼引力场不确定性概念及菲涅耳系数，发现DSWH喉部菲涅耳系数与质量无关，且因观察者位置不同，物体呈现身份可能不同。

最近有人认为，在半经典引力中，一个最小的二维球面不是视界，而是虫洞（如达穆尔 - 索洛杜金虫洞，DSWH）的一个微小喉部，有一个自由参数\(\lambda\neq0\)将其与史瓦西黑洞（\(\lambda = 0\)）区分开来。DS表明，他们的无视界虫洞可以模拟黑洞的许多性质。假设观察黑洞模拟器等同于观察黑洞本身，我们提出一个问题：在单个实验中，观察者可能观察到的物体身份是虫洞还是黑洞。为了回答这个问题，我们通过将引力场描绘为折射介质引入了唐赫利尼在引力场中的不确定性新概念。然后我们假设观察到的物体身份将取决于探测该物体的光子运动的概率结果。概率将由唐赫利尼基于普通光学介质中光子运动的非量子统计不确定性推导的菲涅耳反射（\(R\)）和透射（\(T\)）系数来描述。通过将这种方法应用于引力“有效光学介质”，我们得到了两个有趣的结果：（i）DSWH喉部的菲涅耳系数与质量\(M\)无关，仅取决于参数\(\lambda\neq0\)。（ii）对于相同的\(\lambda\neq0\)值，根据观察者的位置，对一个观察者来说是DSWH的东西对另一个观察者可能看起来像黑洞。
英文摘要
It has been recently argued that in semi-classical gravity, a minimal 2-sphere is not a horizon but a tiny throat of a wormhole, such as the Damour--Solodukhin wormhole (DSWH), with a free parameter $λ\neq 0$ separating it from a Schwarxzschild black hole (BH) ($λ=0$). As shown by DS, their horizonless WH can mimic many properties of a black hole (BH). Assuming that observing a BH mimicker is equivalent to observing a BH itself, we ask the question as to which identity of the object, a WH or a BH, an observer is likely to observe in a single experiment. To answer this, we introduce Tangherlini's new concept of indeterminacy in the gravitational field by portraying the field as a refractive medium. We then postulate that \textit{the identity of the observed object will depend on the probabilistic outcome of photon motion probing the object}. The probabilities will be described by Fresnel reflection ($R$) and transmission ($T$) coefficients derived by Tangherlini on the basis of a non-quantum statistical indeterminacy of photon motion in ordinary optical media. By adapting this approach to a gravitational "effective optical medium," we obtain two intriguing results: (i) The Fresnel coefficients at the DSWH throat are independent of mass $M$ but dependent solely on the parameter $λ\neq 0$. (ii) Depending on the location of the observer, what is a DSWH to one observer may appear as a BH to another observer for the same value of $λ\neq 0$.
